| x | ÷ | 5 | = | ( | 100 | × | 100 | ÷ | ( | 100 | + | 50 | ) | ) |
| x | ÷ | 5 | = | 100 | × | 100 | ÷ | ( | 100 | + | 50 | ) |
| x | × | 1 5 | = | 10000 | ÷ | ( | 100 | + | 50 | ) |
| Multiply both sides of the equation by: | ( | 100 | + | 50 | ) |
1 5 | x | ( | 100 | + | 50 | ) | = | 10000 |
1 5 | x | × | 100 | + | 1 5 | x | × | 50 | = | 10000 |
| 20 | x | + | 10 | x | = | 10000 |
| 30 | x | = | 10000 |
| x | = | 10000 | ÷ | 30 |
| = | 10000 | × | 1 30 |
| = | 1000 | × | 1 3 |
| x | = | 1000 3 |
| x | = | 333.333333 |
